CNC Gasketing Explained

There are two main concepts for gasketing: Grid/Pod gasketing and
Spoilboard/Fixture gasketing.

GRID/POD GASKETING

Grid/Pod gasketing is the material, depending
on the type of router that you use, that would fit into the channels of your
router bed table under the spoilboard, or into the channels of your point-to-point
pods. It is intended to rise above the surface of your table/pod by
roughly 1/16”. By putting gasketing around the perimeter of this
area, it ensures that there will not be any air leaks through the sides of
your vacuum area. Instead, it will focus the vacuum flow down through
the intended area.

SPOILBOARD/DEDICATED FIXTURE GASKETING

After gasketing your table/pod, the idea of using fixture gasketing is next. The
concept of doing spoilboard gasketing is not for every customer. When
routing large parts, most router operators will tell you that no gasketing
is needed. And All*Star agrees. But when parts become smaller
and/or narrower, a greater emphasis is needed on maintaining a vacuum seal. That
is where spoilboard gasketing comes into play.

Our line of spoilboard gasketing products vary in three major ways: Thickness,
width and density. While the products and applications may change,
the concept behind each item remains the same. It is to create a perimeter
of gasketing that, when compressed, will produce an air-tight seal. That
air-tight seal produces a suction-cup-type hold on the part that is being
gasketed.

DENSITY, THICKNESS & WIDTH

Our foam products share three common traits: Density,
Thickness & Width. Each characteristic plays its own important
roll in producing quality parts on a CNC Router. Product Codes follow
this format:

CR_06_38

Width: The
tighter the radius that must be made by the tooling the narrower the width
of the sealant should be.

Thickness: The
more warp or texture in the cutting surface the more thickness is needed.Thinner is better than thicker.

Density: Match
the mass of the material being cut to the firmness of the sealant with consideration
for the strength of your routers’s specific vacuum strength. Firmer
density is better than softer density.
